I live in Chilliwack and I would like to know a good variety of a semi dwarf cherry tree to plant. It would be on a south face location in a sandy loam soil.
How tall a tree do you want? Might be better buying dwarf--sweet cherries tend to grow bigger than was desired.
Plant a dwarf. Maybe try 'Lapins' on Gisela, if that combination is sold up there. http://mtvernon.wsu.edu/frt_hort/stone_fruit.htm
